Abstract
The invention relates to an anti-cracking concrete. The anti-cracking concrete comprises the following components in parts by weight: 20 to 30 parts of kaolin, 30 to 40 parts of coarse aggregate, 20 to 40 parts of dickite, 20 to 40 parts of montmorillonite, 15 to 23 parts of sodium bentonite, 11 to 19 parts of fly ash, and 10 to 15 parts of calcium fluoride. The anti-cracking concrete has the advantages that the capability of extreme stress of concrete is improved, the anti-cracking capability of concrete is greatly improved, the usage amount of cement is reduced, the energy consumption is decreased, and the production cost is reduced.
Description
Technical field
The present invention relates to the cement-base composite material of building material field, a kind of anti-crack concrete improving cement slurry pore structure and homogeneity.
Background technology
Engineering cracks has become the focal issue in construction, and wherein the crack problem of mass concrete is particularly subject to pay close attention to.The factor affecting cracking of reinforced concrete is divided into internal factor and external factor.For larger-size flat board thicker mass concrete (general thickness more than 1m, size at about 100m, hereinafter referred to as large-area backplane concrete) for, affect the self performance that key factor is concrete and the foundation restriction power of its crack resistance.Large-area backplane xoncrete structure is thicker due to thickness, being easily formed internal-external temperature difference during hydration reaction, produce temperature stress, especially it is bigger by ground and internal reinforced binding, easily form bigger shrinkage stress and ftracture, the crack resistance of concrete is required the highest.
Summary of the invention
The technical solution adopted for the present invention to solve the technical problems is: provide a kind of anti-crack concrete, it is characterized in that: include Kaolin, coarse aggregate, dickite, montmorillonite, sodium bentonite, flyash and calcium fluoride, its feed components by weight, described Kaolin 20-30 part, coarse aggregate 30-40 part, dickite 20-40 part, montmorillonite 2 0-40 part, sodium bentonite 15-23 part, flyash 11-19 part and calcium fluoride 10-15 part.
As preferably, described anti-crack concrete, it is characterized in that: its feed components by weight, comprises Kaolin 20 parts, coarse aggregate 30 parts, dickite 40 parts, montmorillonite 40 parts, sodium bentonite 15 parts, 11 parts of flyash and 10 parts of calcium fluoride.
As preferably, described anti-crack concrete, it is characterized in that: described coarse aggregate includes rubble, particle diameter is 15-25mm.
As preferably, described anti-crack concrete, it is characterized in that: the powder containing quantity of described rubble is 5.2%, the mould degree of counting accurately of rubble is 1.5.
As preferably, described anti-crack concrete, it is characterized in that being prepared by following method:
(1) good various raw materials are configured by weight ratio；
(2) the various raw materials configured are added in stirred reactor one by one, be evacuated to 0.2MPa, under conditions of rotating speed is 60rpm, stirs 2h, can be prepared by anti-crack concrete.
The present invention can improve the ability of concrete limiting strain, thus is greatly improved concrete capacity against cracking, reduces cement consumption, energy efficient, reduces production cost.
